(1-Isopropyl-1H-pyrazol-5-yl)boronic acid CAS 839714-33-9

Description

The occurrence of (1-Isopropyl-1H-pyrazol-5-yl)boronic acid is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(1-Isopropyl-1H-pyrazol-5-yl)boronic acid (CAS 839714-33-9), molecular formula C6H11BN2O2 and molecular weight 153.97 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (1-Isopropyl-1H-pyrazol-5-yl)boronic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 153.97 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
